#2798 Risk of Pre-Operative Understaging of Duodenal Neuroendocrine Tumors at Conventional Imaging: When Surgery Becomes the First Choice

Introduction: Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors that can exhibit aggressive behavior, with loco-regional nodes and distant metastases. Pre-treatment staging is the basis for planning either surgical or endoscopic treatment.

#2736 Second Primary Neoplasms in Patients with Neuroendocrine Neoplasms (NEN): DATA from a Retrospective Multicentric Study

Introduction: Patients with sporadic gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NEN) may exhibit a higher risk of second primary tumors than the general population.

#2691 Somatostatin Analogs in Patients with Zollinger Ellison Syndrome (ZES): An Observational Study

Introduction: Zollinger Ellison syndrome (ZES) is a rare syndrome caused by gastrin hypersecretion from a primary neuroendocrine tumor (NET), usually located within the duodenum or into the pancreas. Gastrinomas have two important treatment goal: the control of the gastrin-excess state and the control of tumor growth.
